如何在swiper.js中更改滑动方向? [英] How to change swipe direction in swiper.js?

问题描述

当我将扫掠器旋转90度时，我正努力改变滑动方向.因此，默认情况下，开始时它具有水平方向.单击幻灯片时，我正在旋转雨刷容器"，使其变为全屏显示.因此，它仍然具有从左向右滑动的方向，但是我需要从上到下更改，而无需将参数方向更改为垂直.

I'm struggling with changing swipe direction when I rotate my swiper on 90deg. So in the beginning by default it has horizontal direction. When clicking on slide I'm rotating "swiper-container" making it full screen . So it still has swiping direction from left to right , but I need to change from top to bottom without changing in params direction to vertical .

const topSwiper = new Swiper(this.DOMTopSwiper.current, {
  spaceBetween: 0,
  observer: true,
  observeParents: true,
  observeSlideChildren: true,
  direction: "vertical",
  navigation: {
    nextEl: ".top-swiper-button-next",
    prevEl: ".top-swiper-button-prev",
  },
  pagination: {
    el: ".zoom-amount-slides",
    type: "fraction",
  },
})

推荐答案

销毁先前的Swiper并重新初始化Swiper，以提供方向值.这是文档

Destroy previous Swiper and reinitialize Swiper giving the direction value. Here is doc

演示

DEMO

let isVertical = true,
  direction = 'vertical';
let swiper = initSwiper(direction);

function initSwiper(direction) {
  return new Swiper('.swiper-container', {
    spaceBetween: 50,
    pagination: {
      el: '.swiper-pagination',
      clickable: true,
    },
    direction: direction
  });

}

function changeDirection() {
  isVertical = !isVertical;
  direction = isVertical ? 'vertical' : 'horizontal';
  let slideIndex = swiper.activeIndex;
  swiper.destroy(true, true);
  swiper = initSwiper(direction);
  swiper.slideTo(slideIndex,0);
}
